Electronic smoking device accommodating generic cigarettes

Abstract

Provided is an electronic smoking device accommodating a generic cigarette for generating less harmful aerosol and improving smoking flavor and quality. The electronic device comprises a cylindrical cigarette receiver, an extractor for retrieving smoking substances from cigarettes, a heating unit for baking the smoking substances instead of burning the substance, an air tight aerosol accumulation cavity to collect the vapor for a user to smoke, an electronic control circuit board and a power supply.

What is claimed is: 
     
       1. An electronic smoking device, comprising:
 a cylindrical cigarette receiver; 
 an extractor; wherein the extractor includes an elongated portion positioned within the cigarette receiver, with a body connected to a shank; the body comprises a pair of a carving ridge and a flute having a downward angle and helically wrapped around the shank to facilitate retrieving smoking substances and transferring them downward out of a cigarette; 
 a heating unit including at least one heating element for baking the retrieved smoking substances to generate a desired aerosol; 
 an air tight aerosol accumulation cavity with a sloped first opening air tightly coupled to the cigarette receiver and a second opening air tightly coupled to the heating unit; 
 an electronic control circuit board and a power supply. 
 
     
     
       2. The electronic smoking device of  claim 1 , wherein the shank is attached to a driver for enabling a motion pattern to facilitate retrieving the smoking substances from the cigarette; said motion pattern is selected from a group consisted of rotation around a main axis, longitudinal motion, vibration, or wobbling. 
     
     
       3. The electronic smoking device of  claim 2 , wherein the driver is an electric motor. 
     
     
       4. The electronic smoking device of  claim 1 , wherein the elongated portion further comprises a tip with an angle <60°; when the cigarette is fully inserted into the cigarette receiver, the tip is anchored onto a filter of the cigarette to stabilize a mouthpiece of the cigarette. 
     
     
       5. The electronic smoking device of  claim 1 , wherein the body of the extractor extends along a main axis beyond a bottom of the cigarette to facilitate transporting the retrieved smoking substances to the heating chamber through the air tight aerosol accumulation cavity. 
     
     
       6. The electronic smoking device of  claim 1 , wherein a range of the diameter of the body inside and outside of the cigarette receiver is 2-7 mm and 2-9 mm, respectively;
 wherein the diameter of the body outside of the cigarette receiver is larger or equal to the diameter of the body inside of the cigarette receiver. 
 
     
     
       7. The electronic smoking device of  claim 1 , wherein the cylindrical cigarette receiver is designed to accommodate cigarettes with diameters in a range from 3 to 8 mm. 
     
     
       8. The electronic smoking device of  claim 1 , wherein the heating element is selected from a group consisting of an electrical resistive heating element, an electromagnetic inductive heating element, and infrared emitters. 
     
     
       9. The electronic smoking device of  claim 1 , wherein the heating element is attached to an enclosure of the heating unit. 
     
     
       10. The electronic smoking device of  claim 1 , wherein the heating element is placed inside of an enclosure of the heating unit. 
     
     
       11. The electronic smoking device of  claim 1 , wherein the heating unit is detachably attached to the second opening of the aerosol accumulation cavity; said heating unit has one opening with an operable lid for feeding the retrieved smoking substances to the heating unit when the lid is open and the heating unit is attached to the air tight aerosol accumulation cavity; said one opening allows for disposing used smoking substances when the heating unit is detached from the aerosol accumulation cavity. 
     
     
       12. The electronic smoking device of  claim 1 , wherein the cigarette receiver is air tightly coupled with the first opening of the air tight aerosol accumulation cavity with a slope; an angle between the slope and the main axis of the receiver is larger than 135°. 
     
     
       13. The electronic smoking device of  claim 1  further comprising a thermal insulator enclosing the heating unit to maintain an adequate baking temperature for the retrieved smoking substance and to provide a comfortable temperature for a user to hold the smoking device. 
     
     
       14. The electronic smoking device of  claim 1  further comprising user interfaces coupled to the electronic control circuit board to enable a user to control the temperature of the heating unit for an optimal smoking flavor. 
     
     
       15. The electronic smoking device of  claim 1 , wherein the heating unit includes an inlet and an outlet;
 said inlet includes a first operable lid and is air tightly coupled to the air tight aerosol accumulation cavity, wherein when the first lid is open, the retrieved smoking substances move into the heating unit, and when the lid is closed the retrieved smoking substances are prevented from spilling out; 
 said outlet includes a second operable lid and is located on a bottom of the heating unit for disposing used materials. 
 
     
     
       16. The electronic smoking device of  claim 15 , wherein the lid of the inlet has a first set of through holes to allow the desired aerosol generated from the heating unit to be transferred to the air tight accumulation cavity and the lid of the outlet has a second set of through holes for air supply to the heating unit.
